Herniation of the mucous membrane of the esophagus through a defect in the wall of the esophagus. It is usually located in the posterior hypopharyngeal wall. Small diverticuli are asymptomatic. Large ones trap food and may cause esophageal obstruction, dysphagia, or the regurgitation of food. Treatment is by surgery or endoscopy.
